On Tuesday, a white South Carolina police officer was charged with murder for shooting an unarmed black man as he fled from the officer. The charges were based on a cellphone video recorded by a bystander.

The video shows the officer, Michael Slager, firing eight shots at the back of Walter Scott as Scott runs away. Scott had been pulled over in his car on Saturday for traffic for a faulty brake light. Initial police reports said Scott was shot as he fought with the officer over the officer’s Taser gun.
